We tried to take the trail that goes around Lake Pavin, but it was closed for too much snow. It's mostly melted now.
The trail on the shady side is open about 1/4 of the way around, so we went as far as we could.
The lake itself is frozen over. There were a bunch of scientists in the middle working on something, but we didn't go all the way out. I'll write more later after work.
